Abstract: A molding system for forming an article of composite material including a track, a mold supported on the track, the mold defining a mold cavity, an injection tube supported adjacent the mold and in fluid communication with the mold cavity, the injection tube being fluidly connected to a source of the composite material, wherein the composite material is fed into the mold cavity via the injection tube and wherein the mold is adapted to move injection tube as the composite material is fed into the mold progressively increasing the volume of the mold cavity.

Abstract: A moldable heterogeneous composite material has a continuous plastic phase (30) and a discrete phase of unground rubber (20) dispersed in the continuous phase. The composite material can be formed from thermoplastic or thermosetting materials and pieces of rubber from used tires. The composite material of the present invention can be molded in a process having the steps of providing a flowable melt of plastic material (50), providing unground rubber pieces (70), mixing the plastic material with the rubber pieces to form a composite material, and molding the composite material into an article (10) having a desired shape. Molded articles formed from the composite of the present invention have high rigidity and good durability.

Abstract: This invention permits flat articles to be fluid conveyed from one operation to a point where another operation occurs such as curling, stacking or feeding to a capping machine. The flat articles are moved in a preferred embodiment in essentially parallel rows to an opening in a tunnel conveyor by fluids moving primarily in parallel alignment with the rows of flat articles and prior to their complete entry into the tunnel are contacted on each flat side by streams of fluid to change the angle of movement of each articles, by about 30.degree. and preferably 90.degree. more to move each article to exit of said tunnel with part of the streams of fluid being vented through openings in the tunnel.
